You multiply 3x - y = 3.
So then it's:
6x - 2y = 3
-2x + 2y =6

which equals 4x = 9

Match each mathematical expression with its simplified form.<br> (2 +9+4)<br> (3 + 1 + 4 + 8)
katen-ka-za [31]

Answer:

15 and 16

Step-by-step explanation:   To get simplified form, you add the numbers in parentheses together. (2+9+4)= 15 and (3+1+4+8)=16

For problem 1. 2+9=11  11+4=15

For problem 2. 3+1=4    4+4=8   8+8=16

Hopefully this helped, and please add me as brainliest.

Graph this inequality on the number line.<br><br> x ≤ 2.6
pantera1 [17]

x ≤ 2.6 would look like this on the number line, the 2.6 part would be shaded in as well and not left open since x is less than OR EQUAL to 2.6

2. IQS = 4 and QR is a perpendicular bisector of TS , determined which of the following claims is true
Pavel [41]

Answer:

RS=5 TRUE

RS=4 FALSE (it’s 5)

ST=10 FALSE (it’s 8)

QR=4 FALSE (its 3)

Step-by-step explanation:

First, we have to determine the sides of the triangle.

4x-3=2x+1

4x-2x=1+3

2x=4

x=2

SO, RS=4x-3=4(2)-3=8-3=5

RT=2(x)+1=2(2)+1=5

QR=4²+b²=5².    16+b²=25.    b²=25-16.    b²=9.     b=3

CLAIMS:

RS=5 TRUE

RS=4 FALSE (it’s 5)

ST=10 FALSE (it’s 8)

QR=4 FALSE (its 3)
